'VEHICLE-WHEEL AND BRAKE-DRUM STRUCTURE.

Original application led lay 14, 1125, Serial No. 30,154. Divided -and this application led April 26,

, 1928. Serial No. 104,555.

The primary object of the invention is to provide a vehicle wheel of the disk t pe to which a brake drum structure is attac ed in such a Way as to make up a simple, economical and strong assembly.

Further objects and advantages of the invention will be in part obvious and in p art specifically pointed out in the description hereinafter contained which taken 1n conjunction with the accompan .ing drawings, discloses a preferred embo iment thereof.

Such embodiment, however, is to be .con-- -sidered merely as illustrative of th'e principles of the invention. In the drawings- Fig. 1 is a face view of a vehicle .wheel constructed in accordance with the 1nvention.

Fig. 2 is a central transverse section through lsuch wheel taken on line 2-2 of Fig. 1, looking in the direction of the arrows.

Fig. 3 is a perspective view showing detached one of the sections which make up the disk of the wheel.

Figs. 4' and 5 are fragmental perspective views showing detached certain ttings which are mountedon the disk for the pur pose of attaching the rim thereto.

Fig. 6 is a erspective view showing the P the ttin which appears at the bottom of Fig. 4 whi e Fig. 7 is a similar view of a lug which en ages 'the part shown in Fig. 6.

Fig. 8 is a perspective view of apart of the rim. i

Fi s. 9 and 10 are detail plan views showing t e fittings which appear respectively at the bottoms of Figs. 4 and 5 mounted 1n operative position on the disk.

The wheel consists in general of a hub member l 'to which are secured a plurality e of sector like sections 2 which are suitably secured to the hub at their inner ends. As shown the hub member is I preferto ben each-ofA the sections 2 to' some extent out of the plane of the wheel vas a whole in order to provide reater strength. As shown each plate is nt to vwith a lcomplementary U-shaped rovided with al circular flange 3 upon Whic the inner por.

form an obtuse angle with its a ex 7 substantially at the central line of tlie plate.

I also prefer to provide interlocking parts along the side edges of adjacent plates which assist in holding the plates in proper relation to each other and also stren hen the disk toa substantial eiirte'nt. As s own, one kside edge of each plateis provided with a lip 8 and the other side edge is rovided ange l9; thus in assembling the wheel successive plates are laid down around the hub member 1 with ian es 8 and 9 interlocking to make up a disk having alternate depressions and ridges on each side, the apices 7 forming the ridges on the outside of the wheel and the anges 8 and 9 being located on the inside of the wheel. Preferably the peripheries of the plates are struck up to provide arcuate ridges 10 which when assembled form a metallic felly. The parts 2,may all be made identical in shape and ldimensions, enabling each plate to be pressed out in one operation from the'same pair of dies.

In accordance with another feature of the invention the brake drum is so constructed and supported from the remainder of the Wheel structure as t0 enable an annular strap mounted upon the disk structure of the Wheel to -be employed as the drum. As shown, the brake drum 11 consists merely of a metal stri form and upon the disk structure; in the present form of the invention the fiange 3 of the hub which in ei'ect` forms a part of the disk structure is rovided with an annular shoulder 12 to w ich the drum 11 is suitably secured as by bolts y13. Thus replacement of the brake drum involves only the substitution of a new strip of steel corresponding to member 11, instead of the replacement of pendicular to theplane of the wheel upon a v slight ano'ular movementl of the rim relative which is lshaped into circular emountably fastened iii place.

to the wlieel; and in conjunction with the above locking, devices I provide further.

clamps which when tightened serve to imparts may be suitably part to the rim the slight tightened motion which is necessary to lock the two plates to gether. Preferably, also, the above clamping and locking devices serve to reinforce the joints between adjacent plate members 2.

In the illustrated embodiment of the invention the locking devices and parts above mentioned are located at alternate joints between the-plates 2, there being three of the locking devices and threey of the clamps, as shown in Fig. 1. The locking devices consist of smallfittings 14 (shown in detail in Figs. 5 and, 1 0) having flanges 15 which embrace flanges 9 en the plates and are suitably secured thereto as by the rivets indicated in Fig. 10. The fittings have ledges 16 which are .received` in peripheral notches 17 (Fig. 3) of adjacent plates l2 andY such ledges are provided with T-shaped slots 18 (Fig. which receive headed studs 19 on the inner surface of the rim 20 when the latteris slid on to the felly of the wheel. Thus if the rim be then rotated slightly relative to the wheel, the heads of studs -19 will lock behind the walls of slots 18 to prevent movement of the rim sidewise of the wheel.

The specic type of clamping device employed is shown more in detail 1n Figs. 4, 6, 7 and 9. Referring to Fig. 4, for example, there is shown the angle piece 21 having a wedge shaped seat 22, which rests upon the outer surface of adjacent platesv'2, and a ledge 23 which is received within the corresponding notches 17 above mentioned and has a pair of ears 24 which overlie the flange 9 corresponding thereto. The above secured together by olts or rivets which 1t is net deemed necessar to describe in detail. A

clamping bolt 25 projects outwardly from seat 22 and when the rim 20 is slid in place each bolt 25 will be received within an elongated slct 26 of a wedge piece 27, a corresponding number of which are secured tothe inner side of the rim. In the position which the rim first assumes when studs 19 are received in slots 18, the wedge pieces 27 will -not be trul alined with the wedge shaped seats 22 o angle pieces 21, but when the rim and wheel are c amped 4together as by tightening up the nuts 28` on bolts 25, the resultant wedgmg action between members 22 and 27 Will cause the rim to turn slightly relative to the wheel and thus lock studs 19 in place, as well as independently clamp the rim and wheel together.

Preferably the angle pieces 2l are also `providedwith'bevelled surfaces 29 (Fig. 6) which cooperate with the corresponding bevels 30 on wedged iece 27, to draw the rim down firmly against the felly `of the wheel when the clamps are applied, and I also prefer to provide the inner surface of- 'the rim 20 with an annular shoulder 31 (Figs. 6 and 8) which abuts against the apices 7 of plates 2 whenthe rim is slid into proper position over the wheel.

This application is a division of my coending application Serial Number 30,154 filed May 14, 1925 entitled Vehicle Wheel.

While a specific embodiment of the invention' has been disclosed it is obvious that many chan es may be made therein without departing from its principles as set forth in the following claims:

1. A disk type wheel comprising a, hub member having a flange radiating outwardly a substantial distance therefrom, sectorlike sectionsksecured at their central portions to one side of said flan e to make up a disk, the other side of said ange carrying an annular brake drum support and an annular member secured to said support to constitute aI brake drum whereby the brake drum structure reinforces the wheel structure.

2. A disk type wheel comprising a hub, a supporting member radiating outwardly a substantialdistance therefrom, disk sections lyinfr against one side of said supporting memlber and secured thereto, the other side of said member carrying an annular brake drum support, and an annular member detachably secured to said support to act as a brake drum.

In testimony that I claim the foregoing, I have hereunto set my hand this 16th day of April, 1926.

PHILLIP A. WHITE.
